Encore Glitches

[LauraMay1985]

I'm having problems lately with Encore CS6 and I'm desperately hoping someone can help me find a solution!

I usually send my timelines to Encore from Premiere CS6 and transcoding it to be written to a DVD. During the transcode/witing process something goes wrong because the final product has seemingly random glitches in it. Sometimes 3 or 4 in a 1 hour video. The source and transcoded files are absolutely fine.

I've since tried to export the timeline from Premiere as MPEG2DVD and import it to Encore. I am still getting glitches in the final product, albeit in different places!

Can anyone offer an explaination as to why this might be happening and even better, a solution or workaround/alternative? Without knowing the cause its very difficult to find a fix - I'm now getting behind on projects and beginning to panic!

Thanks in advance,

Laura

What kind of source footage do you have? Frame size and frame rate? What export settings do you use from Premiere Pro?

I know that there was issues when one used 720p50 footage and downscaled it to SD for use on a DVD.

[LauraMay1985]

Source footage is HD 1920x1080 25fps from a Canon XF105.

The export settings are MPEG2-DVD, matching source attributes and maximum render quality. It downscales to 720 which has never been an issue before. I haven't yet tried to write the disk having changed it to 1920, although I'm not sure if that will change anything if its not historically been a problem.

I managed to fix a glitch in a previous as it was just before a cut point in the video. So I adjusted slightly making sure there was a different section of video over the glitch point and it disappeared, thankfully it didn't reappear anywhere else. The problem I'm having now is that the glitch is right in the middle of clip rather than at a cut point so trying that isn't an option in this case. Besides I think that was a more-luck-than-judgement solution before anyway!

[Averdahl]

What Export Settings do you use? Please post a screen dump.

O.k, thanks! All settings seems to be ok though i would have used a higher bitrate and CBR instead of VBR. But this was not about bitrate and changing would probably not fix this issue.

You wrote "I'm having now is that the glitch is right in the middle of clip rather than at a cut point so trying that isn't an option in this case." and to reduce time and trying to pinpoint the issue; What happens if you just export this scene with the same settings and create a brand new project in Encore and import the file as a Timeline and then burn the disc?

Use In/Out Points or the Work Area Bar to isolate the scene you have issues with.

[LauraMay1985]

Hi, thanks for the suggestions. I've just done that - exported a 25 second section around that area, authored to a DVD folder and it came out fine.

I also tried the media encoder idea last night and although the original glitches weren't there after the authoring, they did appear elsewhere!

[Averdahl]

Then i would have tried this:

Create a brand new projcet in Encore and import all your finished media. When you import the media Encore is indexing the files and during that time, do not touch the files or anything else in Encore. Just wait for the indexing to be done. When the indexing starts the file name will be seen as italic in Encore.

I have seen problems when not waiting until Encore has finished indexing. 

Try that and report back! 🙂

[LauraMay1985]

Thanks for the suggestion. I had to export a new version because the current one wasn't indexing in Encore (presuming it was being recognised). Put the new version in first thing this morning, left it to index. Authored a new folder off and, there is still at least 1 glitch - different places again but still coming out in the video! It just seems to so random...

[Averdahl]

If you import the source clip you used in Premiere Pro and place it on a timeline and locate the place where the glitch is in Encore and navigate through/back with the Arrow keys, can you see the glitch then?

As i mentioned i have had similar issues and in let´s say VLC the source footage looked ok but in Premiere Pro it was visible when using the Arrow keys. This was a way for me to confirm the the glitch/glitches were actually created by Premiere Pro and not Encore. There was a nasty bug for years in the MainConcept encoding code in Premiere Pro that manifested itself when one downscaled HD to SD.

Having that said, i would try another encoder. Download Lagarith Lossless Video Codec and export your project to that codec as 1920x1080, 25 fps, Upper Field First. Use the AVI exporter. Then, download the free trial of TMPGEnc Video Mastering Works 7 and import the exported file into it. Then use the "MPEG for DVD File Output" and use the settings in the attached image.

Yes, it sounds insane and it will take time, it will require HDD space, but at the moment i have no better ideas. If it was a 10 second file you could just send it to me and i could test it here, but one hour 1080 Lagarith will be huuuuge. The randomness in this problem is realy problematic.

If someone else have a better solution, please chime in! 🙂

[LauraMay1985]

Thanks, I'll give that a go this afternoon.

To update: Just tried the MPEG2 file in Premiere and it's fine, so I authored another DVD folder in Encore and the authored video is glitching again. I then brought the VOB file into Premiere and it's fine. So I brought the VOB file back into Encore and authored from that. Same glitch, same place.

[RobShultz]

Can you send it to Media Encoder and then convert it to MPEG2DVD? I've had better luck doing this sometimes.

[LauraMay1985]

So export the timeline to encoder and export from there as MPED2-DVD under the DVD drop down menu?

I'll give it a go, but the exported file from Premiere is fine in any case, as is the transcoded file if I do it direct to Encore. Do you think it would make any difference doing it via Media Encoder isntead?

[Ann Bens]

Encore and Premiere use the same engine.

Only difference is Premiere will tell you if something goes wrong. Encore just quits.

[LauraMay1985]

Hi Ann, thanks for you message. 
Would you mind elaborating to explain why this is causing the problem with the authored video? If you can help with the cause I can try to find a solution.
Thanks.

[Ann Bens]

Have you tried going through AME?

[LauraMay1985]

I have, same problem just glitching in a different place in the video this time

[Ann Bens]

Make new project and import old one, then try again.

[LauraMay1985]

How do I import an Encore file into an open Encore project? I tried to drag it across from the folder but a message popped up about not having correct decoders.

[Ann Bens]

No not Encore but Premiere: make a new Premiere project and import the old one and export again.

For Encore it might be wise to start over.

[LauraMay1985]

I've already tried that as well. That's how I narrowed down that the problem isn't anything to do with the source or what is being exported. It also plays find in Encore. When I transcode it in Encore even the transcoded video is fine. But it's when the files are written to a folder or disk that the problems appear - so it's got to be something going wrong during that process.

[Ann Bens]

Have you tried making an image.

That you can burn to disk with e.g. ImgBurn.

[LauraMay1985]

I have, whatever it writes to, the end product has the same problem. It's been happening since the end of July.

[Ann Bens]

PLEASE FOLKS  USE THE TOP BLUE BUTTON. ANSWERS GET OUT OF ORDER.
