Quality Control Problems

I have a question and i hope anyone can answer this. I own a Canon T2i and after i edit my video footage using Premiere Pro i play it back just to observe the quality. The problem is the outcome of the video. The quality tends to be grainy, dusty, and somewhat dull looking. Is there any way to correct this blurry quality look and give it a HD touch like other videos you seen on Vimeo and on Youtube.
 
I'm assuming that could be one of the errors. It could be the type of video format i'm rendering with Pr. I'mt not really sure.

Errors -
1> Dirty Sensor?
2> Rendering video format?
 
Does the footage look better any prior to editing? What format are you exporting to? What filters/FX are you applying in post? What lenses are you using? What lighting conditions are you shooting in?

There could be any number of factors leading to your footage not having "a HD touch like other videos," so we need to know a bit more about your workflow. A good point to start would be to pinpoint exactly where in your workflow the image degradation is happening - is it right from the beginning or somewhere near the end of your workflow?

Hey Deltoidjohn, i've done some research online concerning the video quality and there were multiple results that i came in conclusion with. One of them was Memory Card. my video quality came out SD rather than HD so when i realize that the memory card i was using was an SD class 4 the videos came out as if i was using a camcorder [nothing wrong with using camcorders, that's a different topic].
Another conclusion i came across was perhaps my video settings on my canon dslr.

right now i'm playing with the settings and this is what i have the camera set on

i have my movie recording size at 1280 x 720 60fp.
1/30 f 4.0
iso 800

idk if this is right or will it work correctly. To answer your questions

Does the footage look better any prior to editing?
Yes before uploading them onto my computer the footage looks crisp and clear just the same as if i was playing it back on my camera.

What format are you exporting to?
i think majority of the footages i've taken when i uploaded them are .mov Quicktime, automatically they're quicktime files. i assume canon is more convenient/compatible with quicktime format

What filters/FX are you applying in post?
i've tried doing Color Correction with Premiere Pro, but prior to adding special filters/FX i actually use the camera's built in filters and there are only filters i use. White Florescent and Tungsten only because i was trying to achieve that so called "Movie Look". The other filters i apply to my lenses are external filters such as my microlenses filters; theres a pink, a tinted filter to control the darkness of colors, and a regular clear filter.

What lenses are you using?
Stock lens that came with the kit, 18-55mm EF IS

What lighting conditions are you shooting in?
during the time i was filming, i would say sunlight in the morning coming in through my room. of course i didn't need my room light on so at that time it was off.

A good point to start would be to pinpoint exactly where in your workflow the image degradation is happening - is it right from the beginning or somewhere near the end of your workflow?
ummm can i say from beginning to end the image looks degrading?
 
Noise in the image is directly connected to ISO. Try to stay under 400.
Your profiles can mess up your color, neutral works for me

Thanks! Any more advice i can consider, really need to learn this stuff since i just started using my camera and just began playing around with the editing softwares.
 
For Post Production what presets/setting should i use to render my video using Premiere Pro, and J Davis i've tried putting my camera's ISO under 400, it got worst. =( I saw more noise vs. having a higher iso. What to do now?
 
Currently, i'm rendering another set of test footage and what i've noticed when i was playing the uploaded footage on my computer before editing in Pr, theres two different qualities from two different video players. With Quicktime, it wasn't giving me the same quality i saw on my LCD screen when recording footage; it gave off a noisy buffery look and dull feel. But when i played it on Windows Movie Player the video maintained the same quality i had on my camera screen when i was playing it back. So another error i figured out was the media player. But for rendering opts idk where it goes from there. i'm just going to have to test and see what the outcomes are.
 
you should get a 50mm lens and get a program called MPEG Streamclip. I had the same problem. try after exporting the video put it in MPEG and export it again. another thing are you exporting in .mov

yes im exporting my videos in .mov and still the video persist in showing alot of noise. what 50mm lens do you use for your camera?

I shoot with the 50mm 1.8. the problem is light light light. you need to invest in a faster lens and lighting. after that you can keep the iso below 400. remember the higher the iso the more noise you will get in certain situations

here is a music video I shoot with a 50mm lens and the 18-55mm with low lighting in some spots. my green screen is not good as it should be as well but i'm only 7 month into this. you can tell the difference.

thanks for sharing friend, yes i realize that it was the lighting that was causing problems for my footages. i've noticed my indoor lighting wasn't as great as my outdoor lighting. so i went outside today during day time and filmed both outdoor lighting and indoor lighting and compared both footages. for the indoor lighting even though i shot footages under ISO 400 it still had grainy and noisy textures in the video. but when i shot outside with the same ISO the footage came out better than i expected and had that achieved "Movie Look"

i have a question do you know how to use the MPEG Streamline software? i downloaded the program after you told me about it.

Thanks for your help Legend. :grin:
 
I use FCP Pro so I reformat my clips from DSLR (.Mov) to Apple DV/DVCPRO to eliminate rendering, and after i finish i use it to format to MPEG 4 for uploading to youtube.
 
It would help quite a bit if you could upload some footage to show us, but it's quite a bit more likely to be operator error than equipment problems.

First, are you shooting in slow motion? If not, you shouldnt be shooting at 60fps. also, ALWAYS make sure your shutter speed is double whatever your frame rate is (I'm pretty sure it's not even possible for you to have been shooting at 1/30 at 60fps, but it should have been 1/120). You can get some interesting effects by going higher, but it's not really recommended unless you really know what you're doing.

Second, try to keep the iso at 400 or below if possible

third, it's entirely possible that you were just missing focus and didn't realize it, shots that are just slightly out of focus can look perfectly fine on the LCD screen on your camera.
