DVD flcker, help	Can't Post

Im having issues, I just burned a dvd and sometime there is some bad flicker, I used Premiere Pro 2.0 to create an avi, lower field firstusing the built in DV NTSC compressor. I had also used ulead media studio pro for a couple clips also. I burned using ulead dvd workshop 2, set the quality to 95% with a variable bit rate at 8000, but it has flicker that is shown only on the tv, doesnt show on the computer. Im burning with a sony sz230 notebook computer 1.83ghz core duo, 2gb ram. are there certain settings with premiere and ulead dvd workshop that will give me the best results?

Why not burn at 100%?

im not sure, i know the preset for high quality on dvd workshop only has a vbr at 8000 at 80% quality, i could have done 100, but im not really sure if it does anything, the space required doesnt change, it only chnages when the bit rate changes

Can you give more detail about the flicker. is it the whole screen, just parts, how fast, etc.

BTW - your bitrate is probably too high. You really should try and keep the video under 7000 as you still need room for the audio to play.

the flicker is the whole screen usually, it resembles choppy slow motion, when i pause the video, a lot of stuff flickers like a bad freeze frame. it doesnt play smoothly like on the computer, the flicker jumps back and forth pretty fast and is worse on pans and moving camera shots, also when i was authoring i set up chapter markers but when i viewed it, the clip that had chapter markers doesnt have any audio. i have not been able to try this on a decent dvd player, right now i am viewing it on an xbox 360, one weird thing is when the controls window is on the screen the flicker is hardly noticable, and when paused it doesnt jump, ill have to try it on a different player tomorrow

Wait, why are you creating an AVI file? Do you put this on the DVD?

i save as avi, but then dvd workshop encodes it to mpeg2 using its encoder. i dont seem to see a direct mpeg2 encoder in premiere pro...

Cheap bastards! They probably don't want to pay the licensing fees to the Motion Picture Experts Group.

I do the same thing. I bring an avi over from Vegas and encode with DVDWS. But all my various settings, no matter what the bitrate, are at 100% quality. That option has more to do with the speed of the encode.

As for your issue, I haven't seen that on an entire video before. Sometimes photo montages with high-rez pictures will exhibit flicker. I usually select 'reduce interlace flicker' in Vegas for montages.

the flicker is the whole screen usually, it resembles choppy slow motion,

Right click the clip on the timeline and select, "flicker removal". If that doesn't work select the deinterlace option. But in reality, I suspect something else because you shouldn't have these problems. UNLESS you really have the slo-mo effect applied to some of your footage. Premiere Pro 2.0's slo motion really sucks and was changed in version 3.

Are you using an old trial version of Premiere or something? You should have the ability to export to mpeg2. (You can actually export right to a DVD with PPro 2.0).

And I wouldn't be letting Ulead's DVDWS encode an already compressed DV AVI from any NLE.

Re: [RT Steele] DVD flcker, help [In reply to]	Can't Post

the most i have slow motion used is 50%, but there are some shots that are at only 90% and seem worse.

all i have for file types in premiere is windows bitmap, filmstrip, animated GIF, GIF, quicktime, Targa, TIFF, uncompressed microsoft avi, microsoft avi, microsoft dv avi, and windows waveform.

the dv avi uses premiere codecs, and the avi uses other codecs.

how do you not use uleads encoder in dvdws? it has to get to mpeg2 somehow right? should i encoded a uncompressed avi in premiere and then let dvdworkshop do the compressing?

You should be able to export to DVD in PP2 (unless you are using a trial version).

I use DVDWS2 and I used to create an AVI file and let DVDWS encode to mpeg2. But since I've been using Vegas, I now use Vegas to render the mpeg2 file (and seperate .ac3 file) and load them both into DVDWS to make the DVD's. This works great, never any problems. You DON'T need to use the Ulead encoder in DVDWS (which I doubt is a real up to date version of Main Concept anyway), you can create your mpeg2 file on any other NLE and load that into DVDWS and it will work fine, plus probably give you a better quality encoding anyway. I'm not a Premier guy, so can't help you there.

You're using the wrong menu option to create MPEG2 materials.

Try: File --> Export --> Adobe Media Encoder. Then choose either "MPEG2" or "MPEG2-DVD". Import the resultant file(s) into DVDWS. Other than remuxing the audio they should burn right to disk without re-encoding them.

And I don't think you have the drive space needed to export an uncompressed AVI. DVDWS wouldn't render it anyway.

Re: [RT Steele] DVD flcker, help [In reply to]	Can't Post

thanks, i just figured out about that menu, i created a mpeg2 test file, but when I import it into dvdws and get ready to brun to a disk, what template do I use ( high quality...bit rate settings. also ulead MPEG.Now encoder is still selected and there isnt anything else to select) or does this not matter, since it is already mpeg file, this template info can be disregarded?

I just burned a quick section of a clip, and there is still some flicker on pans and such. i created the mpeg2 file with the constant bit rate at 7000, lower fields first, would a variable bit rate work better, or changing to upper fields first. also why does the mpeg-2 dvd create 2 seperate files (video and audio) and mpeg-2 does not?

Re: [ryin] DVD flcker, help [In reply to]	Can't Post

One format seperates the video and audio streams. The other doesn't. Keep using the 2 seperate files since you'll be using a seperate DVD authoring application to multiplex them.

Your problem isn't VBR vs. CBR. Something else is wrong. the 7000 bit rate setting is fine. Keep all the other defaults - just use the stock template for now.

Is this 24p footage?

Are you trying to apply slo-mo to fast pans?

Does everything preview correctly (and smoothly) in Premiere?

If you "Export" some of this footage as a Microsoft DV AVI (not uncompressed) does it playback smoothly on your PC?

Are you previewing this on an actual TV? NOT your PC monitor as the mpeg2 playback codecs on your PC might not be up to speed.

Re: [RT Steele] DVD flcker, help [In reply to]	Can't Post

the footage is not 24p. avi and mpeg2 play fine on the computer but not on the tv after burned to a dvd.

i have some medium speed pans but it only has 95% slow motion

would it make any difference to make an iso in dvdws and burn the iso in a different program?

also how do you deal with seperate audio and video files in dvdws? do you add an audio track or something in dvdws and the magically sync up?

PPro 2.0 should be handling that fine. Did you try the "remove flicker" option suggested earlier?

And an ISO will produce the same results since it's using the same file - just a different "wrapper".

So far you're using DVD workshop to encode a smooth playing AVI and it's giving you problems.

Also...

You're using Premiere to encode a smooth playing Timeline and it's giving you problems.

And...

You're using Premiere to encode a smooth playing Timeline to an MPEG2 and it's still giving you problems.

Still sounds like something in the footage or your project settings went south. Are you sure it's set up for a standard 29.97 frame rate? (NTSC DV). If it's trying to encode at say... 24 fps, it will stutter. Check those please.

We're about 2 posts from opening up a trouble ticket. I think Hal gets a 10% cut for this. Laugh

Re: [RT Steele] DVD flcker, help [In reply to]	Can't Post

Yep everything plays fine on the computer, i just burned another dvd last night of all mpeg2 files

(for some reason tho I watch dvdws still convert a couple video files but skipped the first couple, and they were all mpeg2 encoded the same way in ppro)

I tried the flicker reduction and it didnt really do anything.
I did change some of the clips slow motion off so it is back playing at 100% and now it seems fine on the dvd. It seems any clip that has slow motion applied doesnt play smoothly and you can see it jitter or flicker.
it also seems the quality isnt as good with these clips and you can see the interlaced lines on the subjects edge. Is premiere just bad with slow motion on tv's or is it me...

I don't know which version of DVDWS you're using. (I don't use it any more). If it's version 1 I think there's an option for you to tell it not to "transcode" any of the files. Also, I believe both versions WILL rehash the video file if your desired output is of better quality than the initial MPEG file you're trying to burn. I have no idea why it would render some files and not the others unless they are different to start with.

Verson 2 of DVDWS just skips the transcode process of all mpeg2 material with the aforementioned caveat.

Both versions, as I said earlier, will remux the audio (Which is normal).

But version 1 is flaky. (Hence version 2 Laugh

)

Is premiere just bad with slow motion on tv's or is it me...

Version 2.0 is/was bad at this at anything lower than about 75% but some of your tests should've come out just fine so I still think it's in your footage. (Or your DVD player. Try it on another set).

You can also upgarde to Version 3.0 which they totally revamped the time remapping feature in Premiere. Silky smooth results now.

But again, give it another go on a different player/set first. You might also just take some static footage (no pans/zoms) and slo it down to maybe 80%. That I guarantee should be fine using PPro 2.0.

Re: [RT Steele] DVD flcker, help [In reply to]	Can't Post

I am using dvdws 2, I looked closer at the mpeg files on the computer and now I think its rendered that way, but it is more visible on the tv, I also notice the avi files look better quality. the mpeg2 files looks like there is bad interlacing, the edges of the subjects show the lines like little jaggies. I just want my footage to look before it was captured, maybe im looking to hard into this, I havent really paid this much attention to quality detail in my other videos. in previous ones i edited with ulead mediastudio pro and authored with dvdws 2 but also burned on a memorex dvd burner instead of the built in burner on my vaio laptop.

Ah, at last someone else experiencing the same problem I had! It's PP2. If you go back into the project and delete all the preview files and re-render, sometimes it claers up. I have upgraded to CS3 and have no more problems with it....
