    Best Online Video Editing Course 5

    I recently completed the online video editing course with Eshikhon and I am totally satisfied with the experience. The course was comprehensive, well-structured, and incredibly informative. It covered everything from the basics of video editing to more advanced techniques, providing a solid foundation for both beginners and those with some editing experience. The curriculum was designed in a very engaging way as well. I want to express my immense gratitude to our instructor MD. Mostafizur Rahman sir for his clear and approachable teaching style and patience throughout the course. What I particularly appreciated was how responsive and supportive the instructor was providing detailed feedback on assignments, answering questions quickly, and offering valuable insights into the creative process. Lastly, thanks to Eshikhon for arranging such an amazing course including both basic and anvanced editing techniques. If anyone wants to start a career in video editing or wants to level up their already acquired skill, this course is a highly recommended one.

    A Heartfelt Learning Journey at Eshikhon with the Inspiring Farjana Sharmin Nave Ma’am 5

    I'm Saima Jannat. As part of DIMA-Batch-N242-6 of the Digital Marketing course at Eshikhon, my journey has been nothing short of transformative. The Digital Marketing course at E-shikhon is perfect for anyone looking to build their skills. The lessons are practical, well-structured, and designed for easy understanding. A special mention to Farjana Sharmin Nave Ma’am, whose engaging teaching and real-world insights made learning enjoyable. I still remember seeing Farjana Sharmin Nave Ma’am on the RJ Kibria show in 2021 and wished to meet her someday. To my joy, I discovered during my first class at Eshikhon that she would be my mentor! Learning from someone so helpful, friendly, and genuinely inspiring has been an honor. E-SHIKHON offers a supportive environment, and I highly recommend this course to anyone eager to grow in digital marketing. At the end of the course, I am going to miss Farjana Nave Ma’am and my wonderful coursemates, who made this journey even more special.

When I started, I have 7 month knowledge of video editing, but now I feel confident in my skills, and it’s all thanks to him. He goes the extra mile to address any issues and ensures every student thoroughly understands the lessons. This course has been a game-changer for my confidence. Md. Mostafizur Rahman’s patience and ability to simplify even the most complex topics made learning a breeze. The practical examples and hands-on exercises he provided were invaluable. The course covered everything from the basics to advanced techniques, leaving me well-prepared to take on real-world projects. I highly recommend this course to anyone eager to learn video editing.
