Digital Sinage?
Hi All,
I thought that I posted this already but I guess it didn’t go through.
I have a client that I did 3 in house videos for. Originally I was told a loop able DVD for each one. Now I’m told that it’s to be placed on an 8gig SD card and played though their sinage system. This system only plays mpeg2, not mpeg2 DVD. The problem is these videos are 45 minutes long and I can’t render them out under a whopping 50 gig file size.
Has anybody done this before? Is there a way through AE to render these out looking nice and staying under 8 gigs? Other wise I really don’t know what to tell them.
Thanks!

Yes, they tried using the .vobs which played partially then the sound dropped off. They sent me an email saying that the system doesn’t play mpeg2 DVD just Mpeg2. When I re- render using AE’s exporting utility (forgot the name of it)and go to mpeg2, change the settings I still get files that are unbelievably huge! I’m at a loss to try and fit them under 8 gigs.

Ahhh….I see! Yes, I saved the m2v files! Then that is what I will do. Awesome….thanks!

WHen dealing with closed systems such as their signage playback system, it is ALWAYS crucial to ask for a sample of the file that is to be played on their system.
Just ask for a short segment. Then use a software that can show you the bitrate of the audio and video. Some MPEG2 players can do that, otherwise look for a freeware utility that can do this for you.
MPEG2 comes and goes in various denominations for both the audio and video streams. You’ll be hitting the roof if you try to guess your way through.
Also ask for the name (manufacturer and model) of the playback system. Then do a little research over the Web for more detailed information.
Unless the MPEG2 is of an esoteric nature, you should be able to output directly from AE and keep the filesize under 8GB. Just keep an eye on the datarate.
What datarate you choose will again depend on the system at hand. Whatever datarate you are given, always deduct 10-15% to cater to overheads. Also, unless specifically asked for, stay away from VBR and stick to CBR for both audio and video compression. This is to avoid spikes that may cripple or delimit playback of the MPEG2 stream.

Arrrrggghh! Well, I brought the m2v file and wav into AE and tried to render it as an mpeg 2 and the video plays choppy. It’s totally skipping frames, yet when I play the m2v on it’s own through VLC player it plays smooth. I do a RAM preview in AE and it plays choppy. I’m just not getting this.
Any ideas?

For Windows, freeware procedure is to use TMPGEnc v2.525 Free Version (MPEG-2 Encoding has 30 days usage limit owing to licencing – good enough for this project) available at TMPGEnc.net.
Open the program, and negotiate to Files > MPEG Tools > Simple Multiplex.
Select MPEG-2 Program (VBR) as the file type for output
Browse to the elementary streams .mpv for video and .mp2 for audio inputs
Name your output
RunIf your current audio is in .wav form, then use another program eg. Super from eRightSoft, to convert the .wav to .mp2 audio format.
