I don't know the first thing about sample rate, but I've heard that video has (or should have) an audio sample rate of 48 kHz.

I have a song as a wave file with a sample rate of 44.1 kHz, and I'm now gonna make a music video for Youtube. Does that mean I should change the sample rate on my song from 44.1 to 48 kHz before importing it to Premiere Pro, which is where I edit my video? Or should I do it when exporting my video from Premiere Pro? Or should I just leave it a 44.1 kHz?

leave it at 44.1k

Ok. Will it make a difference at all?

YOUTUBE recommended encoding settings for best playback:
Audio: 48Khz or 96Khz Stereo AAC-LC
Video: H264 - Progressive scan (no interlacing) - 2 consecutive B frames Closed GOP. GOP of half the frame rate.
CABAC Variable bitrate. No bitrate limit required, though we offer recommended bit rates below for reference Chroma subsampling: 4:2:0
24,25,30,48,50, or 60 FPS

MP4 container set for fast start.

Overall Bitrate is going to do more damage than anything here.

Audio: 128 kbps for mono and 384 kbps for stereo
Video: you can go from 1 Mbps to 56 Mbps based on delivery size ( 360p up to 2160p )

I'm coming from the sound camp, so please be kind :-) About half way through that long line, I get lost.

We just got a Matrox MXO2 and our camera collection needs to be filled out. (We tried a laptop facing the stage, with a 1600 X 900 display showing its camera in full screen, and using its HDMI output to the MXO2 HDMI input. No luck. One of the MXO2 settings showed two 'half' screens side by side, however, none of the other settings showed anything. Then we switched to the other available camera - a black and white tube-type Panasonic - and tried NTSC through composite. It worked, but I think the tube itself has aged. It used to have a better picture, I think.)

So while we try to figure out the camera situation; in Matrox V/V Tools (our only software at the moment) there is a choice:

"Under Codec , select the codec that you want to use for the capture.
. Matrox 8-bit Uncompressed Captures video to 8-bit uncompressed
format.
. Matrox 10-bit Uncompressed Captures video to 10-bit
uncompressed format. This is the only codec available when using a
10-bit video processing format, and is not available when using an 8-bit
format."

Should we just stay at 8-bit - at least for a while?

best, john

those are the prescribed delivery for best results... in the real world... try a few different tests and determine what works for you, how it was shot, and what you can export with your equipment.

Hi Georgia (and anyone else with experience !),

I just have a few questions about video shooting modes vs final delivery.... with YouTube destination as the goal (while trying to balance maintaining optimal delivery quality vs editing time)

I'm shooting concerts with 3 small Panasonic 'domestic' HD cam-corders...hand-held type with swing out LCD screen (model no. HC V50M) under typically lowish light conditions using tripods.

I've generally been capturing at AVCHD 1920 x 1080/50p and then using Power Director's MultiCam "Sync by Audio" to line up external recorded audio (which becomes the soundtrack) with the 3 camera audio streams. This syncs up the video streams accurately, and allows me to switch between the 3 cameras during render

However I'm using a rather underpowered Core2 Duo laptop for all this, and the editing process takes a long time...not unexpected of course. I've found that by using Handbrake to 'pre-render' the video streams down to mp4 before beginning editing, it eases the load on the edit process quite a bit.

I've found that there's minimal quality loss between my final mp4 edit and the completed upload/playback on YouTube, and I've been careful to use the YT recommended encoding settings you've mentioned above.

So with the quality aspect working satisfactorily, I'd like to streamline the workflow a little.

My main question is...would it be advisable for me to shoot the original video in mp4 (rather than the AVCHD outlined above), which would save me several hours of 'pre- encoding' down to mp4 before I begin (given that mp4 is the final YT delivery upload format) ?

Or would I be throwing away and compromising resolution in the video capture phase by doing this, simply in order to save video editing time (and load on my laptop) ? I'm trying to cut down on bottlenecks in the workflow...but not if it's going to noticeably compromise final video delivery quality.

Thank you for your advice on this in advance

We shoot in AVCHD. Our audio is done at 48 KHz. We have never had a problem with uploading to YouTube and getting good results. I would think that Georgia's approach of test shooting and posting on YouTube would be your best bet if you are looking for the ultimate in quality. FWIW

The YouTube upload format should have zero impact on your capture settings. Record at the highest possible resolution and data/bit/sample rate, audio & video. Export to 50mpbs h.264/48k audio. Premiere has export presets for YouTube.
