Sony Vegas Rendering

06/29/2010 9:18 PM

I wanted to post a tutorial on youtube. It required I patch together several .avi videos created with CamStudio. To see if I could edit my video clips with Sony Vegas, I loaded a clip into Vegas, normalized the sound track, and then 'rendered as .avi' the modified video clip. When I played it back on NERO the video picture shook up, down and around by about 1mm at 10+ shakes a second. I then played the same video clip on the CamStudio Player, and the screen was black through the whole playback time. The audio played ok on both players. Does anyone know what has gone wrong in Vegas to cause such a problem in the rendered video?

Perhaps you could render as something else? mpeg perhaps. I have an old version of vegas and it works ok but you can change so many things! It took a long time to get it to where I wanted it.

I used to record a short clip with different recording settings and find the working playback options and then record the longer movie at that setting.

A bit of expermentation is helpful. It might just be that you need to adjust the frame rate a little bit. Pal or ntsc are framerate options on my computer. They make a big difference.

It might be that the record options on cam studio need changing. I use ubuntu and the older version on ubuntu 8.something of record my desktop records as .ogg and the newer on ubuntu 10 as .ogv Looks exactly the same but youtube only reads .ogg so far. Could be a similar thing.

I think mpg1 is vcd quality and mpg2 is dvd quality. But depending on the input, it is often hard to tell the difference. I hope that is helpful.

It may be the codec problem. Try to update the codecs.

If unable to update, reinstall the same while connected to net, at the end program will checks for autoupdate, say yes to it. Then try to play the movie.

cheers.

I kept digging and sorting and found a solution. I believe I need .avi because I need high resolution for screen capture. VirtualDub allows adding video clips via their File 'append avi segment' option. When VirtualDub processes the two clips into one, the new file takes about 30 times more memory space than the two clips required. I then modify CamStudio to record from the speaker instead of the microphone, I use the CamStudio player to play the combined video clip file, and use CamStudio record to create yet another file, which is very close to exactly the the same, viewing and listening wise, as the first combined video file, but is now the small size of the original video clips. This will make it easy to create a tutorial in small clips, before combining into one video.

I have my old vegas and I think it is great. I do not record avi because it is so big.

On ubuntu 8.1 I have the gtk record my desktop. It records everything on my desktop as an ogg file including sound from the videos that I play there and anything I input through the microphone.

On youtube it uploads as high def and comes out better than anything I did on vegas!

But no takes, or way of improving what I made because I have no ogg video editor.

So all you need for what you are doing is something for windows that does the same thing. Someone else might be able to advise you on that. Youtube still mangles some video in conversion but does a great job on .ogg

Is the original format HD?

I believe AVI is not.

I think either choose a codec that is tested to get the best results from such a conversion, or record the originals in SD, in the future. The only other thing I can think of is an interlacing issue, but I don't know what to check or how to fix.

I have movie studio 9, and an hd cam, but haven't done much with it.

I do know VLC is a great player.. and free.

avi is quite dated and processes files in chunks at a time. you want a different format try wmv

Here's the list of some well-known formats which YouTube supports:

  • WebM files (Vp8 video codec and Vorbis Audio codec)
  • .MPEG4, 3GPP and MOV files - (typically supporting h264 and mpeg4 video codecs and AAC audio codec)
  • .AVI (Many cameras output this format - typically the video codec is MJPEG and audio is PCM)
  • .MPEGPS (Typically supporting MPEG2 video codec and MP2 audio)
  • .WMV
  • .FLV (Adobe - FLV1 video codec, MP3 audio)

If you are a camera or a software vendor, you'll want to carefully review the links below in order to better understand how to optimize your content for YouTube:

From Sleepy

may I enlarge the scope of this thread please?

I have a neighbour who is our local historian and he has asked me for some technical computing help in this area ( video editing).

His needs are simple - he wants to take existing videos and cut out chunks (think advert) to create better viewing for an enhanced digital version of his text version of our local history. Also, perhaps to join segments as well?

He has aquired a copy of Pinnacle but I think that that is overkill and will take a long time to get started. He is 80 plus and I am 70 plus! I am short of Video Editing software and capability! Am more than happy with all sorts of Image editing, generally in jpeg format but also moving to RAW format currently.

Does anyone know any alternative techniques to do the video editing. Forget worrying about digital formats , the material is still in analogue form. Technology should not be an issue as I am sure that we can get the analogue material into an appropritae format to do whatever is possible.

TIA

Sleepy

Pinnacle is an AVID program and some are enthralled with it's use but somehow it doesn't impress me much . I always look to Adobe when media editing is required.

Take a look at the offering of NCH software much of which is free to use.

Actually forum member "Roadrunner" is very adept at video editing and may be of great help to you two too...

bwire,

thanks for the input.

Perhaps I need a contact for Roadrunner or better still could you please forward my post to him, assuming that you have a contact for him?

Thanks

Sleepy

This has been recommended for viewing avi

I'll assume you can use the original clips again or if you saved the the modifications then redo but render as .wmv instead; avi is 18 years old
