[SOLVED] AVSTODVD: Audio plays super fast and green screen at the beginning

[jovopros]

Hello, I'm having trouble converting a movie (.mp4 with AAC audio), the video conversion turns out OK but the resulting audio is completely messed up: it plays VERY fast (chipmunk voices ). I've tried using wavi+aften and ffmpeg+aften but the result is the same.

Also I'm having a minor problem with the ISO files AVSTODVD creates: They play fine but I get a green screen at the beginning for about a second or so. No big deal of course but maybe there's something that could be done to fix that.

Thank you.

There are some AAC mono tracks that may have some issues with ffdshow implementation of libavcodec. If you are using ffdshow, try to select 'libfaad2' instead of 'libavcodec' to decode AAC audio.

Otherwise you can try to switch from A2DSource to FFMpegSource in 'Preferences'/'AviSynth'. That may help to resolve the green screen too.

OK, I will try that. Thank you

Just one question, if I choose FFMpegSource instead of A2DSource will that reduce the quality of the resulting video?

It should not, that's just another way to decode the video/audio streams.

OK. Once again, thank you.

Hi, I hadn't had time this past few days to try to re-convert this movie. I finally did and selecting "libfaad2" instead of "libavcodec" for the audio didn't help (log file included).
I'm currently doing a new conversion, now using FFMpegSource instead of A2DSource. The problem is that QuEnc has been running for about 5 or 7 minutes now and currently it says it's gonna take 15 hours to complete... ! hehe and the number of hours keeps getting higher... 16 now... hehe
I'm not running other programs or anything, I opened Firefox just to post this but the number of hours was already insane. The conversion I did just before this took about 50 minutes to complete (see the log file included).

HELP, PLEASE! (18 hours and 50 minutes to go )

Thank you

P.D. I think the green screen at the beginning was due to the source files being in PAL and the setting I had for the resulting file was NTSC, now I'm selecting that manually for each project so that the system doesn't change and so far no green screens. I've done 5 or 6 projects since I created this thread.
By the way, would it be possible to add an "automatic" option so that AVSTODVD detects whether the file is PAL or NTSC and then converts the movie without changing the system?, you now so that one doesn't have to adjust it manually each time you create a project.



By the way, I see that QuEnc indicates 26 hours left now... so I'm gonna kill that process. I include the log for this aborted project in case that helps.
I converted another movie using FFMpegsource instead of a2dsource earlier today to see how it went and everything turned out fine, took about an hour to convert, so I don't know what the problem could be now

It seems that the FFMpegSource approach was even worst. Ok, that was a try, go back to A2DSource.

Do you have the possibility to upload the mp4 somewhere to make some test?

Yes, I'll upload it

UPDATE:
It's ready, I'll send you the link by PM.

Thanks, I will give it a look ASAP.

Nop, hehe it wasn't that, I guess I was just lucky with those particular files I converted before. I just did a batch with 6 projects, 4 of them have that green screen at beginning, one of which flashes in a very annoying way for about 3 seconds.

Would the log files be of any use for this problem?

[jovopros]

OK, I solved the green screen problem: I selected "directshowsource" instead of "a2dsource" on the "avisynth" tab, and so far I've converted successfully 4 movies that had the green screen at the beginning when using a2dsource.

Maybe this could be included on the help section

Thanks for the valuable feedback

OK, here's how the problem was solved: under the "avisynth preferences" tab I selected "directshowsource", re-installed ffdshow, used Windows7 Preferred Filter Tweaker (suggested by PM by MrC) choosing "ffdshow" instead of the default microsoft codecs and now everything converts smoothly no green screens at the beggining and perfect video and audio with that very problematic .mp4 file with aac audio (32 khz) that prompted me to open this thread.

Thank you _MrC_

_MrC_ I don't know if you saw this on that previous post I made, 'cause there was a lot of information, but I thought I'd ask again

There's already that feature. Of course the input file MUST be a DVD-compliant NTSC/PAL mpeg2 to trigger the message box to change the DVD standard.

Oh, I see. I mentioned it because Convertxtodvd for instance has that feature, but it doesn't have to be a DVD-compliant NTSC/PAL mpeg2:


.avi file 25 fps (PAL)

@jovopros

hence your question should be: would it be possible to add an "automatic" option so that AVSTODVD detects whether the file has 25 fps or 29.97 fps and then converts the movie with the most similar DVD standard (PAL or NTSC)?

Yes, it is possible. I will put that in the ToDo list.



Bye

[jovopros]

Oh, yep

Thanks!
