Make sure the resolution in the sequence is the same as the resolution of your clip. Otherwise you'll need to scale the video to fit correctly.

It's hard to read the text in the screenshot, but it appears that the scale drop-down in the two windows is different. The one of the left appears to say "1,3", and the one on the right appears to say "Full" (which is what you said). That may not be THE answer, but it's something I noticed.

You have specified that you are interested in working on a huge number of videos, if you have a multicore machine and you will use a normal for loop provided by your shell, you will have one of your cores running hot, while others are doing absolutely nothing. This is not ideal. What you should be doing for such a job is using parallel, a tool that allows ...

Use ffmpeg and the "transpose" filter as "poor" suggested. For example, if your files are mp4 and are in the current directory: mkdir -p rotated for f in *.mp4; do ffmpeg -i "$f" -vf transpose=2 rotated/"$f"; done The transpose value can be "1" or "clock" for clockwise rotation, "2" or "cclock" for counter-clockwise rotation. There are other values which ...

It sounds like you're seeing motion blur. For stills you would increase the shutter speed. For video, you need to decrease the shutter angle. Essentially, the shutter angle determines how long the shutter is open for each frame of video. So for video at 30fps, it can never be slower than 1/30th of a second. But it can be faster! For example at 30fps, if ...

Based on this answer you can use ffmpeg with following commands to rotate a video: ffmpeg -i input -vf transpose=2 output To Batch process a folder of movies you can use a programming language of your choice and iterate through the files. I've used linux with python 2.7+ here. You only have to edit folder_movies path, path_to_ffmpeg and set your movie ...

Even a typical lamp with a "daylight"-colored bulb in it can act as a lighting source for your product. I'm sure your boss could spring for one light bulb! If you shoot again with the new lighting, or even without the new lighting, play around with the angle of your product / camera / stool to minimize the reflections.

To get a transparent Quicktime Video: select the composition press Ctrl+M to add it to the render queue, click on Output Module to choose the File Format, select Quicktime Container Format for Video Output, select RGB+A to render RGB and Alpha channel

I have a couple of suggestions that could be of help: 1) Use a polarizer to reduce reflections. You say your boss won't spring for anything else, but you can pick one up fairly cheaply (like under $20 on amazon). If that's really not an option, you can try using some polarized sunglasses in front of the lens, at least to see if it eliminates the ...

You don't say what you're using to edit these videos, but there may be a better chromakey plugin for your platform than what comes natively. Also, again depending on your platform, most editors will allow you to crop the key area (garbage matte) so that the green screen doesn't have to cover the entire raster, just enough to back the product you're ...

iMovie comes free on Mac computers, and it includes all of the features you're looking for. It's also very simple to use. (I used it to make about 300 videos over the last 5 years.)

Not sure, which version you're using and I didn't use PowerPoint recently, but as far as I can remember, there is a video export function built in. Might be worth a try. Also there's a list with free video software on Wikipedia, which you can take a look at. Many of them should work for your purpose.

You're right, at some point it visually looks better to downscale and have a lower rez but less artifacty video. The bitrate where this happens depends strongly on how compressible your content is. One way to judge this for x264 might be to look at the rate-factor. For 2-pass, the x264 output includes the rate-factor. For CRF mode, the CRF value you set ...

Something is only properly called "public domain" if the copyright has expired, and there aren't any patents or trademarks applicable either. Many old books are now in the public domain, so it's legal to grab whole paragraphs from them without attribution. (It might still be plagiarism to claim that you wrote it yourself, though.) As I understand it, you ...

Like slhck says, you can compare 2 digital video files with metrics like SSIM. Your question also asked about brightness and contrast, and other things which will depend on the physical monitor that the video is displayed on. If you want to be sure that the right photons come out of the screen, given the pixels it was sent, then you need to calibrate your ...

From my experience all unexpected movements when keyframing are fixed by editing bezier curves of those keyframes, make them linear or something.

You can link multiple clips as you would link two clips. First, put all the audio and video tracks you want in your timeline and arrange them using the timecodes, manual adjustments or however you prefer to align the individual recordings (I'm assuming you have a method for that, since you removed that part of the question in the last edit). Then select all ...

There are quite a few programs that do so-called "full reference" measurement, i.e. comparing an original against a degraded signal: http://www.acceptv.com/en/products_vqa.php http://compression.ru/video/quality_measure/index_en.html (commercial) http://www.its.bldrdoc.gov/resources/video-quality-research/guides-and-tutorials/description-of-vqm-tools.aspx ...

Get a camera with HDMI output and plug it in to a Blackmagic Intensity PCIe card or USB/Thunderbolt unit. Then use Adobe Flash Media Encoder to take that input and encode it into an RTMP/RTSP stream that a computer can easily play on the other via the network, plugged in to a projector or TV.

If you're singing on the new track(s) you've added, definitely! I've done it myself. You can even pan the new track(s) left or right to give your song more "space". If you were thinking you'd take duplicate your audio track in Garageband, and change the pitch of the new track, it's harder. Your harmonies probably won't stay the same number of half steps ...

Movies have certain "looks" to arouse certain moods. The lightning and color depends on the intention of the movie and each individual scene. Let's take the picture you linked as an example: The footballer is lit by the floodlights in the stadium. He is lit from every side so that you can see as much as possible, there is little shadow and contrast. The ...

Just use an affine transform for the title Create a title with the text Put the video on track 2 Put the title on track 1 Combine them with an affine transformation On the affine transformation, add 4 key frames for a title of 5 seconds, at 0 / 1 / 4 / 5 seconds Set the opacity for keyframe at second 0 and second 5 to 0. Keyframes at second 1 and 4 keep ...

There are several websites that do that. For example, this one accumulates free stock photos and there's also a video section. However, your best bet is to use a designated search engine like the creative commons search site, which will allow you to find material distributed under creative commons licenses. Before you use any of the found material, make sure ...
