incomplete renders

#1

Hi–

I’m very new to AE and am just picked up CS5 to learn, and naturally have problems with my first project.

I recorded a lecture in HD with my Canon Vixia camera and need dumb it down for the web. My first step was to drop it into AE, scale it down and reduce the audio quality then output to FLV.

The project is set up to do this and it runs for several hours, but when it’s done the final FLV isn’t complete. I’m missing about 10 minutes of 50 from the end of video.

I’m running Win 7 with 6GB ram and 400gb of free drive space so none of that seems to be an issue.

Any ideas?

Thank you!

Make sure the output of your comp lines up with the end of your footage. You can go scrub to the end of your footage and hit N to set your comp’s out point.

Not sure if you know this or not but you can also scale down and decrease audio quality in the render queue settings instead of in the comp itself.

Thanks for the reply, Timmay. I double-checked the comp and it’s all there, but that has gotten me in the past.

Also, I have changed the output settings in the render queue. My hope was just to dump this directly to a FLV in one step and it mostly worked except for the missing piece.

Unfortunately, I went back to my old method (TMPGEnc Xpress then Adobe Media Encoder) and it worked out, but took, literally, all day just to encode.

BTW…how do you people charge for this? Do you charge hourly for render time, a set rate or how?

Thank you again!

After Effects’ encoder is not very reliable when it comes to compressed container formats.
I usually render out simple image sequences (like compressed TGA) and then run it through a proper encoder together with the audio track.

If you have a CUDA capable card you can try a CUDA compatible encoder which can reduce your encoding times more than half.

That’s good to know, Swahn.

I’m not familiar with CUDA but will look into it.

My other thought was to render the 2GB chunks from my camera separately then join them after, but it seemed like a waste of time. TMPGEnc Xpress can scale, crop and reformat my different pieces while outputting to a single file, though not FLV. It’s easy enough then to drop that file into the Adobe encoder for the FLV, but still a step I’d like to skip.

Guess I have a lot to learn yet.

Thank you both for your feedback.
