HDV=>H264 720x480

[zoobie]

Hey -

Curious what minimal bitrates everyone is using when making 720x480 16:9 H264 mp4's from HDV m2t

[Baldrick]

I use constant quality/quantizer encoding mode if I don't need an exact file size.

[zoobie]

I don't have my editors hooked up at the moment
I'm using WinFF and getting good results @ 1000kbps...
Just wondering what minimum bitrates everyone else is using at 720x480 resolution that's acceptable to them...
I realize each and every clip is different

HDV i do at 864x480 and for most online vids 2 pass 512,000 ave 764,000 max. is quite acceptable.

that's 512 & 764kbps?

[minidv2dvd]

yes, 512kbps ave 768kbps max 2 pass. works fine, especially on servers with low outbound bandwidth.

Forget bitrates. Do what Baldrick suggested. Use constant quality encoding. You'll always get the quality you specify. A 2 hour still frame might get 30 kbps. A 2 hour whitewater rafting video shot with a head mounted camera might get 30,000 kbps. Both will have the quality you specified.

that wouldn't work at all for streaming video. how many servers will allow 30mps per outbound thread? the quality you produce has to be dependent on the final product desired.

Did he say he was streaming?

[minidv2dvd]

did he say he wasn't?

[zoobie]

Well, I've always allowed the viewer to d/l the video allowing smooth playback.

To me, streaming has always been a vague attempt at security...like the video was just too valuable that the server needed a special setup to "protect" it from copying...OR...to simply allow the viewer to watch as the packets arrived assembling the video before their very eyes. This would take away any suprise factor in the video if there was one.

I've never seen a smooth streaming video even at the library with a T3 connection...ever...even from major news agencies. They've always been interrupted by the delivery.

Comments?

[minidv2dvd]

streaming smoothly has more to do with the server end, as in does it have enough bandwidth to push out all the videos' bitrate times the number of people viewing at the same time. you could have your own oc-30 and not receive un-interrupted video when the server at the other end can't handle the load.

I rarely have jerky video with streamed video. When I do it's usually obvious it's from an overloaded server. Like watching live video of Mars landings and such. About once a month I get congestion with Netflix streaming videos around prime time.

Filesize is a huge problem uploading as I'm on dialup
Fortunately, my clips are usually under 10 minutes

I think I'm going to wrap my 720x480 HQ h264/mp4 in a JW Flash player
This way, the player's included in case they don't have the mp4 codec

I'm thinking Arbys

[minidv2dvd]

if you are using the jw player on a website you run then that is a streaming server. they will need an adobe flash plug-in for their browser either v9 or 10 i believe. it will have the codec to play the vids.

What?
Nobody likes WinFF anymore?
