Young Aspiring DOP.
Here are some thoughts:
Rework your video tags - Stifle Bangla Short film short bangla short film new bangla short film bangla short story bangla video best bangla short film award winning bangla short film award winning short short film 2017 bangla new student short film bengali short film short film bengali bangladeshi short film bangla short movie বাংলা শর্ট ফিল্ম বাংলা নাটক - Those are the current tags. Lots of repeated stuff or pointless stuff. Re work them to feature phrases that relate to your film that you think your audience would search in YouTube or Google. I would also remove any single word tags. You want to focus on long tail keywords.
Video Description: You need to massively beef that up. Add a few more paragraphs and try to feature some of the most important phrases you used in your tags. Also, add social media links etc.
Content: Make more content based around your film. Do a Director and/or DP commentary, interview with the actor etc. Treat the channel like the special features on a Blue Ray. The added content will help bring in more people and help explain more about you and your film.
Get out there and promote, but don't spam. You can post links to your film in forums or sites that are meant for that. You can also start leaving solid, helpful on entertaining comments on other related videos. The idea is to start discussion and be helpful.
These podcasts are almost listenable. There is far too much compression and bass in the audio. Sounding overly radio isn't necessarily a good thing, especially in this case.
The way the audio is mixed in these podcasts makes them unlistenable. Too much compression and bass. The voices sound fake and hollow. Please work on the audio. Sounding super radio like isn't necessarily a good thing.
